Dave i am genuinely interested as to your belief that Newtons second law is relevant.
Newton's Second Law can be summarised as (F)orce = (M)ass x (A)cceleration.

So in your glider example, pulling up into a climb (acceleration) is the result of a force with a vertical component (lift).

I can't really put it any more simply.
